That would have happened in countries such as Russia and China, but not in the European Union. Open season has been declared against natives in the EU. The migrants can do whatever they want, and later they can avoid imprisonment by claiming that they are below the legal age.
I live in a European country and unfortunately this is true. Lately many of such incidents have multiplied and governments are trying to hide or mitigate them. If you are speaking against immigrants then you are considered a racist and generally you feel like as a foreigner in your country.
Many such incidents are happening, but the media is banned from reporting these incidents. The racial origin and nationality of the rapists are excluded from the news articles most of the times.
If there were no information given about the perpetrator, you can bet it was an immigrant. And they wonder why the right is rising, and why people have come out with various conspiracy theories like white genocide. By the time the native manage to rebel against their governments, it would be already to late for them as they'd already be outnumbered. Ironic that many of these countries used to have empires.
I live in the Philippines and I don't think this will ever happen here. The government here gets lampooned by people in social media at the mere whiff of concession to Islamists.
When Myanmar expelled their Rohingya Muslims, our neighbors basically ping-ponged them. If we were ever forced to take them in, I doubt they'd be given special treatments like if they were sent to Europe.
